Old. This has been around for ages.

Where did ya learn this!

And yes, the discriminator got served.

He got served! (the discriminator,that is.  I'm not being racist)

A black man walks into a cafe
one early morning and noticed that he was the only black man there.
As he sat down, he noticed a white man behind him.
The white man said, "Colored people are not allowed here."
The black man turned around and stood up. He then said:
When I was born I was black,"
When I grew up I was black,"
When I'm sick I'm black,"
When I go out in the sun I'm black,"
When I'm cold I'm black,"
When I die I'll be black."

But you sir..."
When you were born you were pink,"
When you grew up you were white,"
When you're sick, you're green,"
When you go out in the sun you turn red,"
When you're cold you turn blue,"
And when you die you turn purple."
And you have the nerve to call me colored?!"

The black man then sat back down and the white man walked away embarrassed...
